This is yet more stuff that arose during the design of The Butchery but was mostly not used for it. It is a set of BMP files containing 32x64 or 64x64 panels that cross-product various DOOM texture designs across other backgrounds in DOOM than the ones they were designed for.

For example, the pipework in TEKGREN4 and METAL4 doesn't have a COMP variant, so I made one. I then split it into top and bottom sections so that several variations were possible, in particular I could have created 128 or 256-wide textures or wall patches in various combinations.

The total number of combinations is HUGE, so I decided to release these only as individual parts and let people make their own as needed from them.
